\[df = n_1+n_2-2=40+38-2=76 \] 以\(\nu=76、|t|=|-1.2508|=1.2508\) 为输入通过程序T Score to P Value Calculator计算,可得出\(P=0.21484\)。 确定结论 \(p=0.21484>\alpha=0.05\), 故不拒绝零假设\(H_{0}\),差异无统计学意义。没有充分理由说明两个乌龟物种的平均重量不相等。 Pyth...
A t test compares the means of two groups. There are several types of two sample t tests and this calculator focuses on the three most common: unpaired, welch's, and paired t tests. Directions for using the calculator are listed below, along with more information about two sample t tests...

One Sample t-test 单样本t检验用于检测一个总体的均值\(\mu\)是否等于某个特定值。通常该总体均值\(\mu\),未知不易测量,我们通过抽样得到样本均数\(\bar{X}\)来代表总体均数\(\mu\)。通常抽样存在一定误差,不太可能等于总体均数\(\mu\),所以我们需要关注样本均数\(\bar{X}\)与特定值之间的差异是否存...
